used in the optical path of laser marking machines, laser welding machines, and laser cutting machines.

Half reflect mirror is a semi transparent mirror with a reflectivity and transmittance of about 50% each. It can reflect a portion of the light back while allowing another portion to pass through. commonly used to split laser beams into two different optical paths. For example, in laser marking machines, half mirrors can use one part of the beam for marking or engraving, while the other part is used for monitoring or alignment
